Re: SSHD user-switching under Cygwin/XP (was Re: Case insensitivity ad nauseum)

[David Wood]

Now I'm really out on a limb, but, what user is sshd running as before it 
switches? Does logging into sshd without a password, using a key instead, 
merely mean that no switch from this "default sshd user" occurs? If that's 
the case, can we adjust the "default user" that sshd runs as?
